Astrophotography with the Sigma 14mm F1.8 Art lens
As an astronomer and science filmmaker, I have been photographing the night sky and astronomical observatories professionally for more than ten years. I have photo-documented more than thirty science research sites around the globe in remote places such as the South Pole, the Atacama desert, the South African Karoo, and a lab almost one mile underground in South Dakota. dpreview.com »
